As someone who lost two babies I can't imagine anything worse that announcing a pregnancy on Facebook. But that's what Zuck and his cronies just did.
Now you can add a "new family member" that hasn't been born yet, even with a due date. Because, you know, that's exactly what you want to do, tempt fate by announcing your not-yet-born child, have everyone congratulate you on your wall and then, if something horrible happens, have to take your unborn child out of the list of family members. And of course, have morons write in your wall how sorry they are about your loss.
Really smart. [The Mary Sue]
